Song Tao nodded: "I have heard of Professor Guan Lingling, a professor at the Jingshi University and a scholar in the Yangtze River, she is the real expert."

"Yes, she is indeed amazing." Li Yuan said in admiration: "At that time, she came here for several months, and later asked her assistant to carry a sack of sapphires back."

Li Yuan recalled the situation back then: "About four or five months, or half a year later? She came back and said that there was a plasma implantation method that could transform the color of sapphire."

"We didn't believe it at that time. Later, the people in the county came forward and said that it was true. We were indeed shocked when we got these treated sapphires. They were originally black, but now we can finally see the blues."

Song Tao nodded. Guan Lingling's plasma implantation method is quite famous in the academic community, so he naturally knows it.

This method is specially tailored for sapphires in Yingqiu County. A part of titanium salt is injected into the surface of sapphire, diluting the iron content and making the sapphire more vivid.

"Then there is no change in sales after using this method?" This is what he is more concerned about. Logically speaking, plasma implantation can improve the color of Yingqiu sapphire, and sales will naturally increase.

"It's rising." Li Yuan was quite excited when he said this: "After processing, the price of our gems remained unchanged, but the sales volume increased by 30%. So we were all motivated at that time, and the Gem Commercial City was also built at that time."

Song Tao nodded and said, "That's not bad. Generally speaking, the gems that have been processed are not popular in the market. It is a miracle that you can increase sales after processing."

However, Li Yuan said unwillingly: "Why can they sell sapphires in Myanmar and Sri Lankan at that price, so ours can only be sold at this cheap?"

Song Tao did not comment.

The four most precious gems in the world are diamonds, sapphires, rubies, and emeralds.

Among them, sapphire is the largest category. To be precise, sapphire and ruby ​​are the same variety, both called corundum, red corundum is called ruby, and corundum of colors other than red is collectively called sapphire.

In other words, the color of sapphire is not just blue, but also yellow, green, purple, orange, and even pink.

The sapphires in other mining areas are colorful and beautiful, but the sapphires in the camping hill are black, so it is naturally impossible to enter various international jewelry exhibitions and become the pearl of the upper class socialites and HF supermodels.

This is not possible.

Song Tao comforted: "Our country is not a country that produces gem minerals. Although your sapphires are not of high quality, they are still the only one in China. Why compare them with those countries that rely on exporting gems?"

"You see that there are so many countries in Africa that have diamond mines, but so many people compete for it. Have you never watched "Blood Diamond" starring Li Zi? The mining area has already flowed into a river. We are safe and stable here, much better than them."

"If there was no such mine, Yingqiu's economy would not be even worse. It would be better than not." Song Tao said this and smiled.

Li Yuan sighed. What Song Tao said was something. If the quality was not improved, it would be something that no one could change. No matter how much he complained, it would be useless.

"By the way, expert Song." Li Yuan's eyes lit up and he asked, "You are the expert sent to the head of the department this time. Do you know what the attitude is in the department now?"

Song Tao looked at Li Yuan and the expectant look of the workers behind him, and couldn't help feeling helpless. If he really paid enough attention, could he be sent alone?

But Song Tao didn't want to disappoint them, so he said: "The department now wants to concentrate on solving the problem of sapphire color improvement, but this matter is difficult to deal with, so it may take a long time."

"And don't have too much expectations for the final result. After all, Professor Jian has not been involved in this matter for many years, so there has been no progress in research, and it is very likely that he will end in failure." Song Tao gave them a vaccination.

Li Yuan nodded and said, "We understand this."

Then, under the leadership of Li Yuan, Song Tao visited the mining area. It has to be said that the sapphire particles in Yingqiu are indeed large enough and the inside of the crystal is clean enough. If the color can improve, it will probably be a rhythm that goes against the will of heaven.

While visiting, Song Tao also took a few photos with Li Yuan. There must be such a formal thing, otherwise there will be no way to report it.

Before leaving, Li Yuan gave Song Tao a sapphire worth ten carats. If it was a high-quality sapphire produced in Sri Lanka, the price of such a piece would be at least hundreds of thousands, but it was not.

Song Tao originally planned to shirk Li Yuan, but he couldn't stand Li Yuan's enthusiasm. In addition, Yingqiu's sapphire was not that high, so he would just stop it. Before getting on the bus, Li Yuan kept reminding Song Tao to ask him to visit again as soon as possible.

The driver who picked up and dropped off Song Tao this time was still the same one yesterday. He was sent by the county to be responsible for Song Tao's travel in the past two months.

"Secretary Song, how are you investigating today?" the driver asked casually. In fact, normally he could not actively talk to these leaders, but Song Tao is relatively young and approachable, so he started chatting with confidence.

"The situation is not very good. It's a bit difficult to deal with the sapphire in Yingqiu." Song Tao frowned. Yingqiu sapphire has too much color element content, so it's easy to add it, but it's more difficult to get it out.

The driver said in an unsurprising tone: "That's right, I'll tell you quietly that the county is planning to sell ownership of part of the minerals."

Song Tao asked in surprise: "Does this meet the regulations?"

The driver smiled and said, "There is nothing inconsistent. As long as it can boost the economy of the county, I believe the department can also approve it."

However, Song Tao denied: "I'm afraid this plan won't work. According to the current situation in Yingqiu mining area, no one dares to touch anyone who takes over will be unlucky." Although Song Tao's words were straightforward, they were all true.

The driver thought for a while and nodded: "You are right."

After the chat, Song Tao fell into deep thought. It was normal to say that others had no solution, but he was an exception. If you have any questions, just ask the system. Anyway, there is still a lot of crystal energy left now, and it won’t cost much to exchange knowledge once.

But the problem is that everything must be purposeful, and he is not a bad person. He must have certain benefits to do such time-consuming and labor-intensive projects, otherwise it will not be a waste of time.

"Since the department attaches great importance to this matter, I might as well set up a project. To be honest, I have not really led a scientific research project by myself so far." Song Tao thought to himself.

If you have not hosted a major scientific research project in your resume, it is equivalent to "Calories" that have not been injected into your soul.
